BUILT-IN CHIMNEY II\ TGINERATOR.

Application filed June 4,

This invention relates to certain new and useful improvements in incinerators of the type wherein a brick or like chimney has the incinerator constructed as a built in feature at the lower end thereof, the incinerator being especially adapted for house or apart ment use and having receiving doors or refuse chutes in the chimney adjacent the kitchen of each apartment.

One of the principal objects of the inven tion resides in the provision of the inner wall construction of the incinerator chamber wherein the same has projecting ribs or extensions spaced from each other and extending vertically in the incinerator chamber to increase the draft around the several grate sections for the purpose of promoting combustion and to reduce the .generation of fumes.

Another object of the invention resides in the provision of a novel grate mounting embodying inclined side grate sections that are rigidly supported and an intermediate ]O11I naled grate base section, the operating means for the base grate section being detachable therefrom through the provision o f' an opening through the front wall in the incinerator to permit removal of the base grate section through the charging door of the incinerator.

Another object of the invention is to pro-' vide in an incinerator of the type above set forth, the provision of gas burners of pipe formation extending through the incinerator outwardly of each inclined grate section and with a pilot pipe section associated with each burner.

With the above and other objects in View that will appear as the nature of the invention is better understood, .the same consists in the novel construction, combination and arrangement of .parts to be hereinafter more fully described and then claimed.

In the accompanying drawings, forming a part of this application, and to which reference is had by like characters designating corresponding parts throughout the several views:

Fig. 6 is a detailed sectional view showing the operating rod for the base grate section extending through the sleeve in the front wall of the incinerator and the semi-circular disc-plate sections forming a closure for the outer end of the sleeve. I

Referring more in detail to the accompanying drawings, there is illustrated an incinerator adapted for either house or apartment use, the incinerator body being princlpally of rectangular formation and constructed of fire brick or the like and having a front wall. 1, side walls 2, a rear Wall 3 and an upper wall 4 having a central openmg therein which communicates with the chimney 5 that outlets at its upper end above the roof of the building. The chimney section 5 is disposed adjacent the kitchen wall of each apartment and an entrance door or chute opens from the chimney into each apartment, the door 6 being constructed as illustrated in Figs. 1 and 2.

The incinerator includes a pair of cross bars 7 arranged adjacent the front and rear walls 1 and 3 respectively and at a suitable elevation above the concrete base support 8, the cross bars 7 constituting supports for the several grate sections and the burner pipes. The grate includes inclined side sections 9 seated at their lower edges in notches formed in the upper edges of the cross bars while the upper ends of the inclined side grate sections 9 are angularly disposed as at 9 as illustrated in Figs. 2 and 3. Theside grate sections 9 are permanently supported within the incinerator with the lower ends thereof spaced as illustrated in Figs. 2 and 4, while the horizontal has", grate section 10 is journaled at its ends as at 11 and 12 in notched portions in the cross bars 7.

To facilitate a more perfectcombustion in the incinerator body, the several inner faces .thereof are formed with alternating vertical ridges and grooves, the ridges or ribs 13 being spaced by the vertical grooves 14 that form vertical air passages that surround the several grate sections to permit a substantially. unobstructed draft that IS highly desirable when starting the tire. As illustrated in Figs. 2 and 3, the vertical I'lbS upon the rear wall 3 of the incinerator extend downwardly below the upper edges of the side grate sections to romote the draft at a point in proximity o the burning refuse.

Operating mechanism for the base grate section includes a shaft or rod having a detachable key-engagement 16 with the forward journaled end of the base grate section, while the outer projecting end of the rod 15 terminating at the outer side of the incinerator has a wrench receiving end 17 to receive the wrench or operating handle 18 as shown in Fig. 4. To accommodate the mounting of the operating rod 15, an opening 19 is formed in the front wall-of the incinerator with the rod 15 positioned axially thereof as illustrated in detail in Fig. 6, the opening 19 having a two-part sleeve member formed of companion semicircular sleeve. sections 20'and 21 mounted therein as illustrated, the upper sleeve section 21 carrying a key projection 22 interlocking in a groove formed in the front wall to prevent rotary movement of the sleeve sections.

A disk member formed of semi-circular sections 20 and 21 form a closure for the outer end of the sleeve member and through which the wrench end of the rod 15 projects, the disk member 21 being secured in position by the screw 22 and the member 20" being held in position by any suitable means (not shown). The collar 23 carried by the rod 15 engages the inner face of the disk members and retains the operating rod 15 properly associatedwith the base grate section. When it is desired to remove the .base grate section for repair or replacement, the sections 20 and 21 of the closure disk for the sleeve are removed which permits disengagement of the rod 15 from the key end 16 of the base plate, and at which time the latter may be removed through the charging door opening 24 in the front wall of the incinerator as shown in Fig. 3. The door opening 24 is closed by the hinged door 25, while a door gr'ate 26 hingedly mounted at the inner end of the door opening 24; eliminates flare backs and escape of burning refuse when the door 25 is opened during the use of the incinerator.

The gas burners for the incinerator include a supply pipe 27 communicating with a manifold 28 having valve boxes 29 with which pilot and burner tubes 30 and 31 rev spectively are associated A pipe supportingblock 32 of the type illustrated in Fig. 5 and embedded in the front wall of the incinerator body has a relatively large bore therein for supporting the burner tube 31 having the jet nozzles or burner openings 33, the block 32 further having a smaller bore for supporting the pilot .tube 30 having the burner openings 34. The pilot and burn- From the above detailed description of the device, it is believed that the construction and operation thereof will at once he understood, it being noted that the chimney construction 5 having the charging doors or receiving chutes 6 communicating with the kltchens of the different apartments directs the refuse to thebuilt-in incinerator at the base of the chimney. The refuse collects upon the several gratesections 9 and 10 and the burner pipes 31 positioned outwardly of the incl ned side grate sections 9 have the flamed ets therefrom directed toward the several gratesections for firing the refuse. The alternatlng vertical ribs and grooves alternating on the inner face of the incinerator provide an increase in draft and promot on of combustion, thereby requiring a mlnimum of gas consumptionin the burning of the refuse.

By the provision of the detachable rod connection 15 or the base grate section 10, the latter is readily removable through the charging door 25 for repair or the like. The ash door 37 permits cleaning of the incin erator.

While there is herein shown and described the preferred embodiment of the invention, it is to be understood that various changes may be made in detailsof construction such as W111 fall within the spirit and scope of the invention as claimed.-

What I claim is: j

1. In an incinerator of the type described, a hollow incinerator body having ac ombined chute and chimney extending upwardly therefrom, the body having spaced ridges ararnged on its side walls between the chimney and the lower portion of said body, and forming channels for inducing a draft, a

grate arranged in said body and havin inchned side walls, the major portion 0 the grate side Walls being-spaced from the walls of the incinerator body to provide draft ccnduits communicating at their upper ends with the lower ends of the channels, and burners in said body arranged to direct their flames against refuse in the grate.

2. An incinerator as claimed in claim 1, in which certain of said ridges extend downwardly between the side walls of the grate, whereby the channels between the ast men-
